Filler

Filler is an exciting, entertaining, and addictive puzzle game! Pressing any of the cells will toggle it and the adjacent cells. The goal of the puzzle is to fill the board – switch all the cells on in as few cell presses as possible.

• Fill mode: a random grid with all cells switched off;
• Classic mode: a random symmetric grid with some cells switched on;
• Hardcore mode: a random hardcore grid with some cells switched on;
• Campaign mode: 60 fully unlocked levels (more coming soon);

"Hardcore", "Classic" and "Fill" modes contain random solvable puzzles – in fact, you can practice solving the levels in a few moves as possible using the "Hint" button which shows you the best moves for a given puzzle configuration.
